Good practice

[Dustydazzler]

I always fold over a single cable , it was how I was first shown

but I have worked with loads of newer day sparks who don’t bother folding over cores

I double over all terminations up to 2.5mm where only one conductor is in the terminal.

 

[Lucien Nunes]

bind larger conductors with a core of the said conductor when connecting say as an example a 7/064 into a terminal designed to take a larger conductor

A good shout Pete, many are the times that I've whipped a conductor to make it fit. It's like making your own custom ferrule on the spot. The disadvantage relative to doubling or at least folding back a proportion of the strands is that all the current must flow through double the number of contact surfaces, from core to whipping wire and then to the terminal, but the same applies to a ferrule and isn't a problem if the correct torque is used.

MEM Exels were regular offenders for having terminals that wouldn't clamp down to the minimum size of cable that you might want to use. kWh meters and small tails were another situation.

Not really Sparkes' then?

I have been wrapping tails for years it prevents the conductors shifting. This is a 35mm bond I recently did, wrapped and you can see there is no shift and that is as tight as it goes.

Did you tin the conductor prior to connecting?

 

[gazdkw82]

Any videos on how to do this?

 

[DPG]

I would say don't tin it if it's going to be clamped with a screw fixing.

Why not? ? ? ? three words

No, no tinning.
